A Comprehensive Guide on How to Use an Automated External Defibrillator (AED) | Wellbeing

1. Understanding Cardiac Arrest

Cardiac arrest occurs when the heart ceases to pump blood effectively. A common cause of this phenomenon is a life-threatening arrhythmia known as ventricular fibrillation. This abnormal rhythm typically arises when the heart muscle is damaged by a heart attack or when the heart is deprived of sufficient oxygen. An AED is specifically designed to correct this chaotic rhythm by delivering a controlled electric shock. This technology empowers individuals with no prior medical experience to significantly increase the survival chances of cardiac arrest victims, both within hospital settings and in the community.

It is crucial to note that rescuers must continuously perform Cardiopulmonary Resuscitation (CPR) until the AED is available. Once the device arrives, do not stop; continue rescue breaths and chest compressions while a helper prepares to power on the machine and apply the electrodes to the victim's chest.

2. Step-by-Step AED Operation

For a visual demonstration of these procedures, readers can refer to the instructional video section provided by Wellbeing. The standard operating procedure involves a specific sequence of actions.

First, power on the AED immediately and remove the electrode pads from their sealed packet. You must remove or cut through the victim's clothing and wipe away any sweat from the chest to ensure proper adhesion. Next, peel the protective backing off the pads and apply them to the designated areas: place the first pad on the upper right side of the chest, directly below the collarbone. Place the second pad on the left side of the rib cage, positioned just below the armpit , ensuring the pad aligns with the body's vertical axis. Finally, allow the AED to analyze the heart rhythm. During this critical phase, ensure absolutely no one is touching the victim, and strictly follow the visual or audio instructions issued by the device.

3. Critical Precautions When Using an AED

Safety is paramount during the operation of a defibrillator. You must ensure that no one is in contact with the victim while the machine is analyzing the heart rhythm or when the shock button is pressed. Physical contact during these moments poses a risk of accidental electrical shock to the rescuer and can cause the machine to generate an inaccurate analysis.

Furthermore, never turn off the AED or remove the electrode pads, even if the victim appears to have recovered or regained consciousness. Cardiac arrest can recur at any moment, and subsequent shocks may be required immediately. While the use of an AED can sometimes be complicated by underlying medical conditions, external factors, or the victim's clothing, the safety of all individuals involved must always remain the primary consideration.
